今天我了解了CSS Bootstrap 4，并使用侧边栏创建了我的模板，但是当许多菜单时，我希望侧边栏显示滚动条。
如何在我的侧边栏模板上制作滚动条，这是我的 HTML 和我的 CSS 代码，请帮助我解决我的问题。 我将制作带有滚动和固定的侧边栏
非常感谢

您可以通过简单地添加 Bootstrap 类来做到这一点...
<div class="bg-light border-right min-vh-100" id="sidebar-wrapper">
<div class="sidebar-heading">Start Bootstrap </div>
<div class="list-group list-group-flush overflow-auto vh-100">
<a href="#" class="list-group-item list-group-item-action bg-light">Dashboard</a>
<a href="#" class="list-group-item list-group-item-action bg-light">Menu 1</a>
<a href="#" class="list-group-item list-group-item-action bg-light">Menu 2</a>

我已经修改了#sidebar-wrapper的代码。它将在overflow-y happens时添加滚动条。我希望我能很好地理解你的问题。
#sidebar-wrapper {
height: 100vh; /* Add height */
overflow-y: auto; /* Add overflow-y */
overflow-x: hidden; /* Add overflow-x */
/* min-height: 100vh; */
margin-left: -15rem;
-webkit-transition: margin .25s ease-out;
-moz-transition: margin .25s ease-out;
-o-transition: margin .25s ease-out;
transition: margin .25s ease-out;
}
